Abstract：

Lanthanide　doped　upconversion　nanoparticles　reveal　enormous　potential　for　biomedical　applications.　However,　they　are　limited　by　low　upconversion　efficiency.　In　this　paper,　we　demonstrate　tip-enhanced　upconversion　luminescence　(UCL)　from　a　single　Yb3+-Er3+-codoped　NaYF4　nanoparticle　with　a　maximum　enhancement　factor　of　11　by　the　plasmonic　effect,　which　is　a　solution　for　improving　the　conversion　efficiency　and　will　become　a　potential　technique　for　the　applications　in　sensitive　imaging　and　detection　via　speeding　up　both　the　absorption　and　the　emission　processes　of　lanthanide　doped　upconversion　nanoparticles.　By　investigating　the　optical　properties　of　the　tip-enhanced　UCL　at　550　and　660　nm　separately　in　Yb3+-Er3+-codoped　NaYF4　nanoparticles,　we　observe　that　the　gold-coated　tip　influences　the　upconversion　process　in　Yb3+-Er3+-codoped　NaYF4　particles　by　improving　the　reception　and　the　transmission　of　incident　electromagnetic　fields.　©　2015　American　Chemical　Society.
